Contesting at QRPp levels!


Yesterday I dabbled in the OK/OM DX CW contest for about an hour and a half. This time for some fun and interest I entered QRP level but lowered my power to just one watt. Propagation has been surprisingly nice over the past week or so and I wanted to give the new solar flux a test run. My radio is the Icom 7610 and my antenna is a slopped Endfed antenna at about 25 feet. I stayed on 20m as the radio gods seemed to be smiling on me there. I made only 10 contacts as I was not in the contest for scoring just to see how the fishing was with one watt. I was only asked for repeats regarding my exchange twice other than that the 1 watt made it through. 

Because I was operating at only 1 watt I also wanted to take the loss of my SWR into account. I checked with my antenna analyzer and the CW portion on 20m my SWR was 2.3:1. According to the power loss at various SWR readings chart at 2.3:1, I was in around 15% so this took my 1 watt down to 850 milliwatts. 

Below are the results of my QRPp contest efforts:

RFI issue solved!

Back in May I posted regarding an RFI issue I was having and at the time I thought is was the neighbors heat pump. A few weeks ago my neighbor was away on business and his heat pump was off but my RFI was still present and more of it! I took my Eaton FRX5-BT put it on AM with the antenna up and took it for a walk about. When I passed by my Hydro smart meter the RFI was present big time but last time there was no issue at the meter. Upon investigation I read that the meter has cycles were it transmits data and thus the off and on issue with the RFI. The other issue is we are in very close proximity to other homes and I am certain my Endfed antenna is picking up not just my smart meter. The good new in all this is my Icom 7610 has great filtering and my NB is able to filter it out and the issues are gone. It's a problem that I can live with along side the rigs filtering.

Well here we go again!


On January 15th, 2020 I posted my short ride with Windows 10 installation on my PC.  I was having issues with the upgrade and I decided to downgrade back to Windows 7 pro. It's now 10 months later and I am getting the Windows 10 itch again. I was having sound card issues for my WSJT-X and JTDX programs when using Windows 10.....but I am hoping now those issues have been dealt with. I have also read and seen some YouTube videos on how to stop Windows 10 from doing updates. It seems at times Windows updates cause issues with some ham radio software. This time around if I go ahead with Windows 10 I will do a fresh install and not overtop of Windows 7. 

I am looking forward to the input of those of you who are using or have upgraded to Windows 10 and what has been your experience and what advice do you have?

Followup on computer issue.

 A few days ago I posted regarding a computer issue I was having and asked for some input regarding it. On my blog, Amateur radio.com and a computer geek site I subscribe too I received lots of great feedback. The consensus seemed to be I was having graphic card issues or maybe RAM issues.........or both! Yesterday I decided to haul the PC tower out from within my roll top desk. It's a real pain to do as I have to get in behind the desk and remove off the cabling........but it is what it is. The plan was to take the most common advice I received and look at the graphics card and the RAM. I also updated the graphics card software as it was out of date. 


Right off the but I noticed the graphics card was seated but one clip that snaps the card in place was not engaged and the card seemed loose. I ended up removing both the 2 RAM cards and the video card, cleaned them off and replace them. The inside of the PC was dust bunny free as it was just a short time ago I had it open and cleaned it with compressed air. Once everything was back in place with the side covers still off I started the PC just to make sure the 3 cooling fans, CPU fan and graphics card fan were all running and they were. 


Everything is back together now and it's a wait and see game to see if the issue happens again. Some of the advice I received was that it was about time to purchase a new PC. I agree that mine is not lightning-fast and by no means do I need a gaming computer so it was off to the internet for input. I came across WA7EWC post regarding this very subject. He has great information in his post and one tidbit was regarding the benchmark of your processor. He suggested anything between 3000-8000 and you should be good to go. I bench-marked my processor and it came back with a score of 5340. It seems I am middle of the road and I am happy with that. 


For me to upgrade and with what I want to spend I am just moving up the ladder a tiny bit regarding processor speed and so on. To tell you the truth sometimes you can get lost in the PC specs and speed and the reality is I may not even notice a difference in the speed. To move up to something where I notice a difference means spending close to or over 1,000.00 and I am not prepared to do that. I may end up getting a solid-state hard drive as an upgrade but first I want to make sure the graphics card or whatever the issue is has been solved. I also can overclock or as AMD calls it "turbo speed" the PC to 4 GHz from 3.5 but again that would mean spending money on a new CPU fan as the stock one I have won't cut the cooling required............and will I notice a difference between 3.5 and 4.0 GHz? 


This PC was built by me and I like doing it that way as I get what I want and can tinker with it. I have noticed brand name PC's on the market now there is little room for expanding and I am not too keen on that.

Propagation seems to be picking up.

 


Yesterday afternoon I was on FT8 and was spotted in Tasmania which for me was a great sign of propagation. Then a surprise showed up on the waterfall VK7AC from Tasmania was calling me. We exchanged reports I received -11 and sent -04.

Looking for input on my PC.

 


Today I started my PC and was greeted with the above screen......I did restart and all was ok but I was wanting to hear some of my readers wisdom as to what this could but and more importantly is it a sign of worse things to come?

PC information is as follows:
OS is Win 7 64 bit
The processor is AMD FX-8320 3.5 GHz
Ram 8 GB
Graphics card Nvidia Geforce GT 730

Busy busy busy!

Good afternoon to all my blog readers that is if you have not given up on me and my lack of posting? I have been on and off the radio but not really any news out this way. I will say that this retirement gig sure keeps me busy! I am the type of person that has to be doing something, it's very hard for me to sit idle and listen to the bird's sing.  My hat goes off to those who can sit and just relax, I call it doing nothing but those who practice it call it recharging the batteries. Well maybe sometime I will get to that point but at this point in my life, I like to keep busy. Before I retired I wanted to make sure that when I did I kept busy. To accomplish this Julie and I agreed (as I drive her NUTS if I have nothing to do) to purchase a fixer-upper home. Funny thing when you mention that to a real estate agent their version of a fixer-upper is what I call a "dump"!

We ended up getting a place that needs some "remodelling" and some outdoor stuff done and just enough to keep me busy. There was some outdoor medium to major projects I wanted to complete before the snow flies and down here on the East coast that can be very soon. The projects are now finished but unfortunately, it had put my ham radio activities on hold for most of the summer months. Winter means indoor work and I plan to slow the pace down a bit so that I am not to really tired in the evenings. 

As I look back I have been retired for over a year now and the time is just flying. Before I retired I had a conversation with some gents who were already retired and they told me the following: 

- It is going to take some time getting used too.....very true it took me about 6 months to get into a routine. 

- You will feel less stressed..... to be honest, I did not feel stressed at the time BUT once I retired I began to realize I had become accustomed to the stress level and it was my unhealthy normal. I now can say that I really was stressed and am now much more content. 

- You will forget what day of the week it is........good lord I just can't tell you how many times I have to really stop and think of what day it is.....never thought that would be me! 

You will be busier than when you were when working fulltime........ true that!! 

I am not sure if I missed any retirement life lessons but if I did feel free to chime in. Now that fall is here it's time to slow down sure the projects are still ongoing but I am going to practice the last bit of advice my retired buddies told me that that is "If it does not get done today it can wait until tomorrow or the next day" My next retirement life lesson is going to be.....make sure I fit time in for my hobby as it too is doing something!
